Getting EL variable properties in eclipse

I'm using Eclipse/Spring source to edit JSP tags and EL. If I want to check what all the properties of a variable are is there a way to do this? Or even find out which file is generating the variable that's passed in. I'm thinking something along开发者_如何学编程 the lines of firebug for Javascript, where you can select an object and drill-down to get it's properties.

Eclipse doesn't support EL autocomplete yet. It isn't that smart yet. IntelliJ Ultimate Edition supports it and MyEclipse supports it as well, but both are not free (when talking about JSP/EL development).

The JBoss Tools Eclipse plugin supports it to a certain degree, only for implicit/predefinied EL objects, but not for custom ones which you've put as attribute in request/session/application scope yourself.
